(1) Wasn't there a patch for an extended shell language?  
I seem to remember someone proposing a patch for an extended shell language, or extending the shell
in some other manner.  I couldn't find something related.  Is there such a thing?

(2) A web site listing the source
Is there a web site where one can browse the source online?
